INELASTIC NEUTRON SCATTERING AND LATTICE DYNAMICS OF THE LAYER SEMICONDUCTOR GaS

A. Polian , K. Kunc , J. Rossat-Mignod

Measurements of the phonon dispersion curves of Gas in the Ɖ → M and Ɖ → K → M directions by inelastic neutron scattering have been performed. They show a non dispersive behaviour of the LA phonons in both directions. A Rigid Ion Model (RIM) with anisotropic effective charges and Axially Symetric Forces (ASF) is constructed from these data and discussed.
